How to bind multiple textures?

[nanoqsh]

I want to create a bind group with multiple textures like this:

@group(0) @binding(0)
var t_diffuse0: texture_2d<f32>;
@group(0) @binding(1)
var s_diffuse0: sampler;
@group(0) @binding(2)
var t_diffuse1: texture_2d<f32>;
@group(0) @binding(3)
var s_diffuse1: sampler;

Then I call set_bind_group to render something with this textures:

renderpass.set_bind_group(0, textures.bind_group(), &[]);

But the problem is this bind both textures simultaneously. What if I want to rebind one of them and keep the other? Can I rebind one texture separately? Or I need to create a separate bind group instance?

Why don't I use multiple bind groups? Unfortunately, I don't have such an opportunity, because I ran into a limit on the max number of binding groups (4), because in addition to the texture, I also use the camera, light, etc.
